I'm in (sort of)
Instead of making a game for this LD (and possibly end up with yet another half finished project), I want to spend the time finishing my program Tile Studio II. This is a sprite / tile / map editor based on the old Tile Studio, but completely redesigned.
The program is pretty much finished, but I still have a long list of little things to do. And I need to start making some little example projects and video tutorials that show how to use it (I'm afraid new users might otherwise get frustrated). Also I need to write more export scripts for integration with different game libraries. And finally I still need to make a little website.

This is going to be a paid program, but there will also be a free version with some limitations that is very usable for smaller projects.
